Abstract

Deterministic memory allocation for real-time applications. In an embodiment, bitcode is scanned to detect calls by a memory allocation function to a dummy function. Each call uses parameters comprising an identifier of a memory pool and a size of a data type to be stored in the memory pool. For each detected call, an allocation record, comprising the parameters, is generated. Then, a header file is generated based on the allocation records. The header file may comprise a definition of bucket(s) and a definition of memory pools. Each definition of a memory pool may identify at least one bucket.
